Hi,

Please put this snippet in your child theme’s functions.php:

function ps_rename_group_tabs() {
 
    if ( ! bp_is_group() ) {
        return;
    }
    
    buddypress()->groups->nav->edit_nav( array( 'name' => __( 'Activity', 'buddypress' ) ), 'home', bp_current_item() );
}
add_action( 'bp_actions', 'ps_rename_group_tabs' );

Hopefully, it will help you.

Thanks
